If you choose a champion with a specific aura in a different area, then it's like you're choosing a champion with no aura? If that aura doesn't work in that specific area shouldn't it warn you, that you haven't chosen a champion with an aura?
Hello, this thread is from almost 5 years ago.
And no, it doesn't do this. The system just looks for you to have ANY aura and that's enough. It's up to the player to read the aura effect text on the screen. :)
